DOOR-HANGER.

SPECIFIGATION forming part of Letters Patent 1\To. 231,686, dated August 31, 1880. Application filecl January 30, 1850.

T0 all whom 4115 mag concern:

Be it known that I, SAMUEL SHREFFLER, Jr., of the city of Morris, in Grundy county and State of Illinois, have invented certain Improvcments in Door-Hangers, the constrnc tion and operation of which I will proceed to explain, reference being had to the annexed drawings, and the letters and fignres thereon, making a partof this specification, in whiah Fignre 1 is a side ele"ation; Fig. 2, a front elevation of a roller; Fig. 3, a side elevation of a single hanger; Fig. 4, a eross-sectional view of thetraak; Fig. 5, a plan view of the details of the track, and Fig. 6 a side view of the details of the track.

This invention relates to the construction of the rollers upon which the door hangs anti rolls 'rorn side to side, which rollers may be applied to barn-doors or doors of a dwelling, especially sliding doors and the improvement 1 claim to have made relates to the aontrivance for preventing the rollers from getting out of place and changingtheir distance from each other without their being connected with each other by a reach or otherwise.

In the drawings, B is the sicle of a building, and D is a door of the kind that slicle from side t0 sitle to close the opening.

I) is a rail that is fastened to the side of the building, over the opening just next to and immediatcl5 over the door D, and in length twice the width of the door. On the top of the rail b tl1e track is laid, which track consists of a 1netal strip, 90, or strips jointed together, as shown in Fig. 5, on the top of which metal strip, and along its central line, is a wooden strip, n, (shown partianlarly in Fig. 4 in crosssection,) whial1 strip u is astened to the metal strip by bolts or nails, to ba firm, and serves as a guide for the grooved rollers a to travel over, as is shown in Fig.2in cross-seation, 111e metal strip .10 forming the track upon which the rollers a roll and rest, as shown in Iigs. 1, 2, and 3. The door hangs from the crossbar z 4 5 by the arn1s P P, and the cross-bar irests upon the racks 0 c, one at aither end, which racks rest on the aentral eogged axles, 1, of the grooved rollers a, as shown in Figs. 1, 2, and 3, between the two flanges of the rollers a. These grooved rollers are entirely separate antl disconneated rom each other, and are held in plaee and at the proper distancc from each other by means of the cogged axles r meshing into the aogs of the racks c, as shown in Fig. 1.

When the door is long the constrnction of the frame v2]? may be as is shown in Fig. 3, one al: eaah corner of the door, for greater strengtlx and seaurity.

By constrncting the rollers a in ibis form, and by the nsc of the raak c, 110 jar orjam of the door aan slide the rollers along so the door aan rnn off tl1c rollers, and the door runs so easily a child aan move it.

Fig 6 shows the mode otfasteningthe track (16 and rails n and 1) together loynails or bolts. The metal strip .I) is first nailed to thc. WOOCl guidestrip n at the lower side, and then rhe track tlms form ed of a strip ot' wond and m-etal is nailed or bolted down to the rail b, .as shown in said Fig. 6, which for1ns a rail or track comblll(l of wood anti metal that is very aheap and not liable to break, as when they are made of cast-iron.

Haring tl1us described my invcntion, what I claim. as new, and desire to secure by Letters Patent, is as follows, to wit:

1. The combination and arrangement of tl1c grooved rollers a, central cogged axle, 1, and tootlied. racks 0, for the purpose of snpporting a-nd sliding the door D, in the wanner set 'rth.

2. The track to support and guide tl1c groovetl rollcrsa, consisting of the flat metal strip 00 and wood rail n, attaahed tl1ereto, arranged to op"- 8 5 erate as and in the wanner described.
